The development of morphological structures and morphometric parameters of individual sections of the small intestine was studied in piglets during the milk nutrition and weaning. The most important changes in the small intestine were observed in the period of weaning, i.e. after 28th day of raising. During this period we observed the reduction in height of the villi, and the crypts deepend. The most marked changes were in the medium part of the jejunum, the height of villi achieved only 324 micro m and the depth of crypts up to 230 micro m on 35th day of life. The height of villi was 718 micro m and depth of crypts 84 micro m compared with the milk nutrition on 7th day of life, it was also statistically highly significant (p0.001) compared with the above mentioned values in the period after weaning. The reduced surface of villi in the small intestine during the critical period after weaning can evoke a predisposition of weanlings to insufficient absorption, possible dehydration and conditions for intestinal infections
